The optimization passes for the SSA2 IntermediateLanguage are collected and controlled by the Simplify2 functor (simplify2.sig, simplify2.fun).
The following optimization passes are implemented:
There are additional analysis and rewrite passes that augment many of the other optimization passes:
The optimization passes can be controlled from the command-line by the options
-
-diag-pass <pass> — keep diagnostic info for pass
-
-disable-pass <pass> — skip optimization pass (if normally performed)
-
-enable-pass <pass> — perform optimization pass (if normally skipped)
-
-keep-pass <pass> — keep the results of pass
-
-loop-passes <n> — loop optimization passes
-
-ssa2-passes <passes> — ssa optimization passes
